-      # The set of modules is discovered rather than written out, because it

-      #   repl    - its go.mod replaces cel.dev/expr with ../../cel-spec, a
-      #             sibling checkout that does not exist on a CI runner
-      #   codelab - stale go.mod; `go mod tidy` is needed before it builds
